It carries a continuous current rating of 32 A at 40 °C, with no derating needed up to 50 °C — at 55 °C it still holds 31 A, and at 70 °C it delivers 30 A. That means this breaker handles its full nameplate rating across typical panel ambient conditions without a bump in frame size. The interrupting capacity tells you where it can safely clear a fault: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
The 3VA1032-3ED32-0JA0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into SENTRON distribution panels or standalone enclosures. No rewiring needed if you're replacing a same-frame 3VA breaker; the lug centers and mounting pattern are consistent across the 3VA family.
The rated insulation voltage of 800 V means the internal clearances and creepage distances are designed for systems up to that level — so it's fine on 480/277 V, 600 V, or even 690 V industrial networks. The power loss is 10.6 W maximum, which is modest for a 32 A frame; heat dissipation in a crowded panel won't be an issue.
